Photographic material and process comprising a bicyclic pyrazolo coupler |
| abstract |
Novel bicyclic pyrazolo couplers containing a ballast group of formula (I): <IMAGE> I are useful in photographic materials and processes. The couplers exhibit increased coupling activity, and provide formation of dyes having improved maximum magenta image dye density, contrast, and development speed when employed in color photographic materials and processes. |
